I had 7800 actors in my map and the map was still very performant and lightweight. After one of the Fortnite updates it started to fail cooking. I had to delete random objects until it cooks fine again.
- My project is slightly above 50% it is not lagging so it should cook fine. I should not need to delete stuff so that the error on the server does not happen.
- Cook error should say the reason and if it is specific asset, it should list it, if it is certain number of objects I cannot have, it should say in the error message.
- I think there is no project size report available until cooking passes, so it is hard to decide what to delete.
